  Included in here is:
   - interconnect updates
   - mei driver updates
   - uio updates
   - nvmem driver updates
   - soundwire updates

   - other small misc driver cleanups and updates

  As mentioned, all have been in linux-next for a while, and with the
  last two reverts, all is calm and good"

tty: hvc: Use the correct style for SPDX License Identifier

2020-03-18T12:01:05+00:00

This patch corrects the SPDX License Identifier style in
header file related to the HVC driver.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used).

Changes made by using a script provided by Joe Perches here:

tty: source all tty Kconfig files in one place

2020-03-12T16:17:30+00:00

'source' (include) all of the tty/*/Kconfig files from
drivers/tty/Kconfig instead of from drivers/char/Kconfig.
This consolidates them both in source code and in menu
presentation to the user.

Move hvc/Kconfig and serial/Kconfig 'source' lines into the
if TTY/endif block and remove the if TTY/endif blocks from
those 2 files.

Pull tty/serial updates from Greg KH:
 "Here is the "big" tty and serial driver patches for 5.5-rc1.

  It's a bit later in the merge window than normal as I wanted to make
  sure some last-minute patches applied to it were all sane. They seem
  to be :)

  There's a lot of little stuff in here, for the tty core, and for lots
  of serial drivers:

   - reverts of uartlite serial driver patches that were wrong

   - msm-serial driver fixes

   - serial core updates and fixes

   - tty core fixes

   - serial driver dma mapping api changes

   - lots of other tiny fixes and updates for serial drivers

  All of these have been in linux-next for a while with no reported
  issues"

riscv: don't allow selecting SBI based drivers for M-mode

2019-11-13T21:20:02+00:00

When running in M-mode we can't use SBI based drivers.  Add a new
CONFIG_RISCV_SBI that drivers that do SBI calls can depend on
instead.

docs: powerpc: convert docs to ReST and rename to *.rst

2019-07-17T09:57:51+00:00

Convert docs to ReST and add them to the arch-specific
book.

The conversion here was trivial, as almost every file there
was already using an elegant format close to ReST standard.

The changes were mostly to mark literal blocks and add a few
missing section title identifiers.

One note with regards to "--": on Sphinx, this can't be used
to identify a list, as it will format it badly. This can be
used, however, to identify a long hyphen - and "---" is an
even longer one.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
